Frequently Asked Questions
What shielding benefit does the LSHM-120-02.5-L-DV-A-S-K-TR provide for high-speed board stacking applications?
The LSHM-120-02.5-L-DV-A-S-K-TR includes a conductive shield enclosure that reduces electromagnetic interference (EMI) coupling between the connector and adjacent circuitry. This shielding is particularly valuable in RF-sensitive designs, wireless communication modules, and high-speed digital systems where unshielded board stacking connectors at 0.50 mm pitch could otherwise introduce noise or crosstalk across the 20 signal contacts.
What is the board stacking height of the LSHM-120-02.5-L-DV-A-S-K-TR and why does it matter?
The LSHM-120-02.5-L-DV-A-S-K-TR provides a 2.5 mm board stacking height, which determines the separation between the two mated PCBs. This compact 2.5 mm gap allows components on either board to face inward, maximizing the use of available PCB real estate in thin devices. Designers must ensure that any components placed between the boards fit within this 2.5 mm clearance.
How does the peg mounting option help during reflow soldering of the LSHM-120-02.5-L-DV-A-S-K-TR?
The PEG (peg) board mounting feature on the LSHM-120-02.5-L-DV-A-S-K-TR inserts into pre-drilled PCB holes, mechanically fixing the connector in position before and during reflow soldering. For a fine-pitch 0.50 mm connector with matte tin termination across 20 contacts in a 0.579 inch body, this prevents shifting under solder paste surface tension, ensuring all terminations align correctly and reducing solder defects in automated SMT assembly.
